To give some perspective, I live about five miles from Yorktown National Battlefield, and the flags demarking the American, British, and French positions still fly. We are not trying to hide the fact that France was our benefactor when we needed military support, as Bayeux seems to be doing.
There may well be a reasonable explanation for this, but I cannot think of one that fits within the scope of reason and logic, and that also survives the swift cut of Occam's Razor.
